Write a program that counts from 1 to 15, prints each number and then counts as deuces in the opposite direction to 1, again typing each number.

What does "count twos" mean? Something really did not understand, good people explain!

    Maybe it makes sense to ask this question to the one who set this task before you? - DreamChild

Like so?

for(int i=1; i <= 15; i++) System.out.println(i); for(int i=15; i>0; i-=2) { System.out.println(i); if(i > 1) System.out.println(i-1); }

    Most likely like this:

     for (int i = 1; i <= 15; i++){ System.out.println(i); } for (int i = 15; i >= 1; i-=2){ System.out.println(i); }

    Or so:

     for (int i = 1; i <= 15; i++){ System.out.println(i); } for (int i = 15; i >= 1; i-=2){ System.out.println(i + " " + (i - 1) + " "); }
